In order to solve the problem of evaluating and screening different varieties and different price raw materials before selection and procurement,on the basis of a large number of practical experience,a feed pricing e-valuation system based on the value of energy and protein in corn and soybean meal was innovated,and a value/price ratio was created to screen and compare different raw materials.The procurement system was applied in large-scale cattle farms,which achieved the effect of significantly reducing production costs.
